(E) Important Quotation: "the risk of tipping cascades [to destabilizing feedbacks] could be significant at a 2°C temperature rise and could increase sharply beyond that point. We argue that a planetary threshold in the Earth System could exist at a temperature rise as low as 2°C above preindustrial," from
Will Steffen, Johan Rockström, Katherine Richardson, et al. (2018) 'Trajectories of the Earth System in the Anthropocene.' Proceedings of the National Academy of Sciences (USA) 115 (33): 8252-8259.

(F) Important News:The AAAS awarded the Scientific Freedom and Responsibility Award to Drs. Sarath Gunatilake and Channa Jayasumana who "faced death threats and claims of research misconduct while working to determine the cause of a kidney disease epidemic that has claimed tens of thousands of lives in their home country of Sri Lanka and around the world. Ultimately, their advocacy led to the culprit, an herbicide called glyphosate, being banned in several affected countries," according to a Feb. 4, 2019 AAAS press release. The press release has since been removed from AAAS website. AAAS has also cancelled the award ceremony. US Right to Know captured it and have it posted at this link.
